Abstract

PURPOSE:To resolve many problems that the connection section between a front lens and a housing has a complex shape from the appearance problem, for example, and the lens cut for the side face section of the front lens becomes difficult while a headlight with the shape surrounded by the side face of a vehicle body is required according to the trend of the recent car design. CONSTITUTION:The molding direction D when a housing 3 is molded is made perpendicular to the longitudinal direction M of a vehicle in the structure of a headlight 1, and the side face section 2a of a front lens 2 can be formed nearly perpendicular to the molding direction D. The connection section between the front lens 2 and the housing 3 is not exposed, and a lens cut 2b can be easily applied to the side face section 2a to resolve a problem.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headlamp installed in an automobile, and more particularly to a method of configuring a headlamp.

2. Description of the Related Art FIG. 3 shows an example of the structure of a conventional headlamp 90 of this type, in which the direction D of cutting out a mold during molding is relative to the longitudinal direction of the vehicle as indicated by the arrow M in the figure. For example, a projector-type light body 93 is housed in a chamber formed by a housing 91 formed along the housing 91 and a front lens 92 fitted like a lid to the housing 91. When attaching the headlight 90 to the vehicle body 10, due to structural constraints of the mold forming the housing 91, it is usually done by screwing from the direction along the longitudinal direction M of the vehicle. It has become.

[Problems to be Solved by the Invention] However, in the headlamp 90 having the conventional structure described above, (1) When trying to correspond to the recent trend in automobile design in which the front lens 92 wraps around to the side of the vehicle body, the housing 9
1 and the front lens 92.
The problem is that the lens fitting groove 91a provided in the lens fitting groove 91a is exposed on the side surface, and in order to hide this, the shapes of the housing 91 and the front lens 92 have to be complicated, making it difficult to form them. (2) At the same time, the side surface 92a of the front lens 92 that wraps around to the side of the vehicle body is approximately parallel to the direction of mold removal, so the lens may be used for adjusting the light distribution characteristics or for decoration on this side surface 92a. This is a problem that makes cutting difficult and limits both performance and design. - Space is limited on the outer surface of the vehicle body 10, making it difficult to secure a mounting position for the headlight 90 on the vehicle body 10. This resulted in a number of problems, and the solution of these problems has become an issue.

[Means for Solving the Problems] The present invention provides a headlamp in which a lamp body is housed in a front lens and a housing, as a specific means for solving the above-mentioned conventional problems. The above-mentioned conventional problems are solved by providing a headlamp characterized in that the drawing direction is perpendicular to the longitudinal direction of the vehicle.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained in detail based on an embodiment shown in the drawings. What is indicated by the reference numeral 1 in FIG. 1 is a headlamp according to the present invention, and this headlamp 1 is constructed by housing a lamp body 4 in a chamber formed by a front lens 2 and a housing 3. This is similar to the conventional example, but
According to the present invention, the housing 3 is formed using a mold having a punching direction D that is perpendicular to the longitudinal direction of the vehicle as indicated by an arrow M in the figure.

Furthermore, since the extraction direction D is perpendicular to the longitudinal direction M of the vehicle, the housing 3, that is, the headlamp 1, which is formed at the same time as the housing 3 is molded, can be attached to the vehicle body 10. The mounting boss 3a for mounting is also provided parallel to the removal direction D, so that the headlamp 1 is screwed in from a direction perpendicular to the longitudinal direction M of the vehicle. body 4 light bulb 4a
The light bulb replacement port 3b provided for replacing the light bulb is also provided parallel to the extraction direction D.

Furthermore, since the housing 3 is oriented in the extraction direction D, the lens fitting groove 3c, which is integrally formed in the housing 3 and provided for fitting the front lens 2, is also aligned in the extraction direction D. Therefore, in order to accommodate this, the direction in which the front lens 2 is removed from the mold during molding is also appropriately changed, for example, in a direction parallel to the drawing direction D.

[0008] Next, a headlamp 1 configured as described above is provided.
To explain the functions and effects of the above, first, by making the removal direction D of the housing 3 orthogonal to the longitudinal direction M of the vehicle, the lens fitting groove 3c is not exposed on the side surface, and the front lens This simplifies the shapes of both the housing 2 and the housing 3, and gives a degree of freedom in their shapes, making it easier to expand the degree of freedom in design and simplify manufacturing.

Furthermore, in the front lens 2, since the side surface 2a along the side surface of the vehicle body is orthogonal to the die cutting direction D, it is easy to make decorative lens cuts 2b on the side surface 2a. In particular, it becomes easy to improve the aesthetic appearance of the side surface portion 2a formed due to design requirements.

In addition, by making the removal direction D of the housing 3 perpendicular to the longitudinal direction M of the vehicle, the mounting boss 3
A is also provided on the side with a wider contact surface with the vehicle body 10, ensuring a sufficient mounting area and ensuring reliable mounting.

FIG. 2 shows another embodiment of the present invention, in which the leg portion 21a of the front lens 21 is extended to a position where it wraps around the back of the lamp body 4 on the rear side of the vehicle. At the same time, a light bulb exchange port 21b corresponding to the lamp body 4 is provided on the extended leg portion 21a on the M side in the longitudinal direction of the vehicle by applying a horizontal punching mold method or the like. .

[0012] By doing this, the combined surface of the front lens 21 and the housing 31 becomes almost perpendicular to the respective mold cutting directions, and in particular, since the housing 31 has a shallow dish shape, the structure is simple. At the same time, the light bulb replacement port 21b is provided at the same position as in the conventional one, making it possible to perform conventional procedures such as replacing a light bulb, for example. Note that since the functions and effects other than those described above are the same as those of the previous embodiment, detailed explanations will be omitted here.

[0013]

[Effects of the Invention] As explained above, according to the present invention, the structure of the headlight is made such that the die cutting direction during molding of the housing is perpendicular to the longitudinal direction of the vehicle. Even when the front lens is required to wrap around the shape, the joint between the front lens and the housing is not exposed on the side of the vehicle body, which is extremely effective in improving the appearance and simplifying manufacturing. .

[0014] Furthermore, with the above configuration, the side surface of the front lens, which requires a particularly high level of performance such as a design configuration or lateral light diffusion, can be positioned approximately perpendicular to the direction of mold removal. Therefore, the lens can be freely cut into the side surface, which has an excellent effect on improving the appearance and performance.

In addition, with the above configuration, the headlight can be mounted on the vehicle at a position on the vehicle body perpendicular to the direction of travel, ensuring a sufficient mounting area and ensuring reliable mounting. It also has the effect of
